I am getting placements in cse too.but it seems like engineering is now not worth thats why I am asking this question

Majority of Engineers are job less that's the point of concern before choosing Engineering. 

It's not bsc its bcs...

Although the engineering courses is losing its craze today but still it provides employment to a large number of people in our country and specially IT sector of our country is so broad and provides so much of employment opportunities so if you are considering placement while choosing between the two courses then I would prefer you to go for the B tech course.And if you are confused that whether there are placement opportunities or not then you should check the previous year placements in areas of good engineering colleges of our country.If you get a good college then it is surely going to make your future bright. But if you want to choose BCS then it is also not a bad idea since after BCS you have many opportunities like  you can pursue masters and also go for MCA and other related courses.
